supporting apparatus adapted for removal Vfrom its service position.A

Drawings: Figure lisa side view of a jack constructed and arranged in accordance with' the present invention and showing in conjunction therewith an' autcmobile, the same being supported inl lifted position thereon. Fig.. 2 is a top plan view of a jack constructed and .arranged in accordance with the present invention, one ci' the bosses being sectioned to show the method of mounting the supporting arms therein; Fig. 3 is a detail view on an enlarged scade and in section, the section being taken as on the line 3 3 in Fig. 2; d is a horizontal section taken on the line 4-4e in Fig. 3.

As seen in the accompanying drawings, a jack screw 9 is provided with a suitablel scie'w.-thread to engage a tapped perforation in the'boss l@ of a base plate 11. The base plate l1 is preferably anchored on a cement foundation 12, as best seen in Fig. 3 of .the drawings. Anchor bolts 13 areernployed to hold the base plate ll-in service position.

The jack screw 9 is provided with a headV 14, through which extend perforations 15 provided to receive and hold the end of a winch bar 33.6 employed to rotate the screw 9 to elevate or lower a table i7.

'lhe table 1i is centrally boredI to receive the reduced pivct end 18 of the screw 9. The

' table 17 is directly supported by an annular shoulder formed on the head 14: at the junction ot saidphead with the pivot end 18. Said table is not anchored on the screw9, it being desired that a certain amount of movement on the part of the table should be permitted. Adjacent the outer edge of the table 1'2' a. circular groove is 'provided to forni a race for balls i9.

After the balls 19 are disposed in the race provided therefor, as seen best in Fig. of

is hewn as the washing door, being the drawings, thereon, a, central perforation being provided in said body, through which passes the, pivot end 18.- The body 2O is made lsuiiiciently heavy and strong and has radiated therefrom in substantially opposite and diverged directions, socket bosses 21. Usually there arefour bosses, afs seen best inlig. 2 of the drawings. These bosses are axiall bored to loosely receive spider arms 22. he bosses 21 and the bores formed therein .are sufficiently .long to permit an adn justinent of the arms 22 lengthwise of the soclretsor bores thereof. The adjustment thus provided for permits sufficient expan- 'sionnnd lcontraction of thespider arms 22 to adapt lthe jack .for use on Atarions sizes of automobile vehicles.

At the extreme ,ends of each arm 22 is formed a saddle or crook 26, in which is seated the axleor other suitable` part of an automobile or other vehicle. To reinforce or strengthen the arms 22, they may he provided with atruss bar 23 having a strut 24, or an equivalent construction, such as a'continuous and integral web extending from the under side of each of said arms. twill also be understood that for light Vehicles the truss and equivalent devices may ,be dispensed with.

The body 20 is held in service by a nut 25. v"llhe nut; 25 or other fastening device for .holding the body 20 in position isused only where the jack is retained permanentlyin position to be employed as in large garages where `the jack is generally located on what employed as an accessory to the operation ot washing.

Usually, however, the body 20 and arms 22 are removed trom the screw 9, as is also the winch bar 16. lt thearms 22 are retained in the socket posts of the bosses 21, the spider structure is dis osed of in any suitable manner. Where esired, however, the arms 22 may be removed from the sock ets andl disposed of independently or with the `body 2G and winch bar 16. ln cases where it is desired, it isobvious that the screw 9 maybe reoved from the base late 11, when the door ot the garage will be practically unobstructed.

.The present jack is employed principally as an adjunct te a washing orpainting station, and the foundation i2 is usually the draining door of said station.
